4. Machine Main Structure:

1. Structure type: The lathe is of gantry type structure. The left and right stand column, articulated beam and other large parts are made from high strength, low stress HT250 cast iron. The hardness is HB170-190.

4. Beam: To ensure the accuracy of the machine, the beam is made from high strength, low stress HT300 cast iron. To extend the life of the machine, the contact surface of beam and stand column guideway is made of wearable Zn-Al alloy plates.

6. Speed changing box: The material of gears is of high-frequency quenching handling of high quality alloy steel. The hardness can reach HRC45-50, the accuracy can reach 7 series. The speed changing box is of vertical type and not easy to beat teeth.

7. Hydraulic system: The hydraulic station has blocking, flow and pressure protection, the machine will stop working automatically if it is beyond the reach of operating requirements.
